Embodiment Construction

[0036] Please refer to Figure 1 to Figure 8 , a hydraulic single-point two-way loading test device for anti-rolling torsion bar, including a platform 3-1, a force device installed on the right part of the platform, a double beam lever mechanism installed on the platform, and a left part installed on the platform adjustable support device.

[0037] The double beam lever mechanism is mainly composed of a side rolling beam 1-1, a rotating support 1-2, a rotating shaft 1-3, a shaft sleeve 1-4, a rotating hinge shaft 1-5, a mounting seat 1-6, and a suspension device 1-7 , Oil injection pipe 1-8, M16 fastening bolt 1-9, self-lubricating bearing 1-10, limit block 1-11, M10 fastening bolt 1-12. Its function is to install the anti-roll torsion bar and form the roll angle at the same time. The suspension device is installed on the platform. The rotating support is a trapezoidal support, and its longitudinal section is trapezoidal.

[0038] The adjustable supporting device is mainly...

Abstract

The invention discloses an antiroll torsion bar fatigue test device and method. The antiroll torsion bar fatigue test device comprises a platform, a force application device, a double-cross beam levermechanism and adjustable supporting devices; the right end of the double-cross beam lever mechanism is connected with the force application device; and the adjustable supporting devices are mounted on the front side and the rear side near the left end of the double-cross beam lever mechanism. The midpoints of two side roll cross beams arranged in pairs side by side in a front-back manner are hinged to the same rotating support; an antiroll torsion bar is connected between the bottom surface of each side roll cross beam and the platform; antiroll torsion bars are connected among the side rollcross beams, the adjustable supporting devices and the platform; and a load is applied to the right end of each side roll cross beam, thereby simulating real working conditions for carrying out a single-point bidirectional loading test on the antiroll torsion bar. By means of the fatigue test device and method, the fatigue test can be carried out on a plurality of antiroll torsion bars at the sametime, and the suspension and fixation of different types of antiroll torsion bars can be realized, so that the purpose of improving the fatigue test efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an anti-rolling torsion bar fatigue testing device and method. Background technique [0002] With the rapid development of my country's rail transit industry, high speed, safety and comfort have become the development trend of rail vehicle design and manufacture. The combination of anti-roll torsion bar and air spring is used in the secondary suspension system of rail vehicle, which greatly improves the safety and comfort of the vehicle. The anti-roll torsion bar is an important part of the secondary suspension of the bogie. Its function is to overcome the disadvantage of the air spring with less vertical stiffness resulting in an increase in the roll angle, and to restrain the roll of the vehicle body relative to the bogie. The performance of the anti-roll torsion bar must be tested before use, especially the stiffness and fatigue performance. In order to ensure the comfort and...
